directly upon the vaporization coil. This acetylene-gas burner C is connected to a pipe O',which communicates directlywith an acetylene-gas reservoir R, which in turn isshown as connected directly to an acetylene-gas generator R', which in the present instance is arranged in juxtaposition'with the tank T. Interposed in this pipe C' is a jet c for the acetylene gas, and on the pipe is an adjustable sleeve c', having openings corresponding with similar openings in the pipe to admit air, which, in connection with the acetylene gas, produces a blue or Bunsen flame at the burnerC. This pipe is provided with suitable valves c2 c3 for regulating the flow of the acetylene gas, and` the pipe and burner may be supported in any suitable manner, as by the hood of the lamp (when it is used) or by loops or brackets c4.'

I have found by actual practice that with the use'of acetylene gas in a burnerarranged as above set forth the vaporization-coil can be heated in a very few seconds and at an exceedingly small cost for a great number of times and that the lamp may be set in operation in a very short time.

Connected to the air-intake tube Bis a mixing-chamber tube D, and this is shown as projecting up and through a head B' of the airintake tube B, forming a chamber B2 between' the tubes for the purpose of protecting and keeping relatively cool the nozzle of the vapo-v rization-coil hereinafter described. The other lend of the mixing-chamber tube D projects projected. Mounted in proper relation tol this burner is an incandescent, and while its form and arrangement may vary I have shown it in the form of a mantle G, suitably supported as at G',-so that the flame of the jets from the burner F willimpinge uponthe mantle and produce the desired incandescen ce and consequent illumination.

It is Well known that one fruitful source of trouble in this 'class of lamps is the nozzle through which the vapor of the fuel or hydrocarbon is forced, as it is liable to become clogged, and an unpleasant hissing sound is produced,.and in order to avoid these difficulties I provide an improved nozzle H, attached In the present instance formed on the portion A' is a hollow projection h, into which is screwed,

needle t', mounted on a valve-stem Z, which in the present instance extends through the mixing-chamber tube D, through the plug E' of the mixing-chamber, and through the ring E2, where it is provided with set-nuts i' i2, and the end is provided with any suitable means for operating, as the thu mb-piece Z'. It will be seen that with this construction if there be 'any tendencyto deposit carbon on the interior of the nozzle it will naturally gravitate into the recessed portion H2, surrounding the conical portion h' of the plug, and can be removed by removing the plug, and the needle can be manipulated by` the valve-stem not only to regulatevthe flow of the vapor through the nozzle, but to keep the opening h2 free from any deposit. Moreover, I have found that this form and construction of valve avoids the disagreeable hissing sound so common to lamps of this character.4

It may be remarked that in the drawings I have shown a lamp without a hood ,or inclosing globe, and these may or may not be used, as desired, and maybe of any usual or preferred construction.

The operation of the lamp will be readily understood by those skilled in the art from the above description, and it need simply be stated that in starting the lamp the valve c2 is opened and the mixed acetylene gas and air ignited at the gas-burner C, and this, as before stated, owing to its arrangement and the extreme heat produced by this mixture of acetylene gas and air, quickly heats the vaporizer, so that almost immediately the rool valve t can be opened to admit the hydrocarbon to the Vaporization-coil A, where it is vaporized, and, passing through'the portion A', is projected through the nozzle H and the mixing chamber tube D into the mixingchamber E, where the mixing of the vapor and air coming through the intake-tube B is completed, and thence it passes to 'the burner F, and, being ignited, the ame impinges upon the mantle G, quickly rendering it incandescent and producing the desired illumination. The needle controlling the nozzle can be conveniently adjusted by the thumbpiece Z' in connection with the adjusting-nuts z" i2 and the ring E2.' l

The construction and arrangement of parts are relatively simple and provide a practically right-line passage-way for the vapor and air through the mixing-chamber tube, tend- IIO IZO

Further, it will be seen that the vaporization-tube and the Bunsen burner are practically parallel to each other and are both connected to a suitable source of oil and gas supply and that the Bunsen burner is provided with one or more openings so located that jets of flame projecting therethrough will impinge on the vaporization-tube, the burner being closed at one end.

Having thus described in detail the preferred embodiment of my invention and set forth its mode of operation, it will be seen that I am not limited to the precise details of construction and that some of the characteristic features of my invention Inay be used in combination with other features thereof or with other equivalent constructions and arrangements without departing from the spirit of the invention.
